53SL ES Series Mobile Radio Operating Manual April 2009 4-9
Basic Operation Section 4 - General Operation
For example, Zone 1/Channel 16 is selected by Channel 16, and Zone 2/Channel 16 is
selected by Channel 32.
Proceed as follows to select channels using this mode:
1 Enable the direct Channel Select mode by selecting it via the menu or by pressing the
Channel Select option switch. A single beep sounds when the switch is pressed (if that
option is enabled).The alias and sequential number of the current channel are
alternately displayed.
2
Select the desired channel using the Up/Down keys or directly enter it using the 0-9
keys. A single beep sounds when the channel is changed (if that option is enabled).If
using the 0-9 keys, the radio attempts to display the entered number after the third digit
is entered or approximately two seconds after the last key is pressed.
3 To exit this mode and select the entered channel, press the Channel Select switch again.
This mode is also exited automatically without changing the channel after
approximately one minute of no activity.
Note The Channel Select function should probably not be assigned to a number key because
pressing that key to select a channel then exits the select mode.
Other features of this mode are as follows:
• When using the Up/Down keys, wrap-around to the lowest zone/channel occurs after
the last channel in the highest programmed zone is displayed and vice versa. For
example, if Zone 1/Channel 5 is the highest programmed channel, wrap-around occurs
after Zone 1/Channel 16 is displayed if the “Programmed Channels Only on Display” is
not selected. If the “Programmed Channels Only on Display” is selected, the wrap
around occurs at Channel 5.
• When an unprogrammed channel is displayed, the sequential channel number and
“UNPROGRAMD” are alternately displayed.
• If an invalid channel number is entered using the 0-9 keys, or the Channel Select option
switch is pressed with “UNPROGRAMD” displayed, an error tones sounds,
“INVALID” is briefly displayed, and the displayed channel does not change.
4.1.6.6 Favorite Zone Selection
The Favorite Zone feature allows the radio to be programmed to provide users the ability
to setup “Favorite Channels” in one Favorite Zone, and allows the user to edit the channels
without impacting any of the channels already programmed to the zone.
